WATER-IVI ETE R.

SPECIFICATION forming part of Letters Patent No. 297,301, dated April 22, 1834.

Application {led July 1l, 1883.

T LLZZ u'wm/ it may concern,.-

Be it known that I, NICHOLAS SEIBERT, of Maplewood, county of Middlesex, State of Massachusetts, have invented au Improvement in Vater-Meters, of which the following description, `in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

My invent-ion relating to water-meters is I shown embodied in a meter'adapted to be used Figure l is a longitudinal section ofafluidmeter embodying` this invention; Figs. 2 and 3,

horizontal sectional details thereof on lines .r

and i, respectively; and Fig. 4, a vertical sectional detail on lines z, showing the pivot or 3o step for the measuring-screw.

The apparatus is adapted to be connected with a delivery-pipe for the fluid to be measured, the said tluid being received at the inletpassage la, from which it passes through ports 2 and 3 (see Fig. 2) into achamher, b, having the main portion ot' its interior in communication with the port2, and provided with an outlet, c, the said chamber also having an independent passage, d, communicating with an 4o outlet, e, at its upper end, the liquid passing through the ports 2 and 3, thus being delivered independently through the passagescand e. The port .2is of greater width than the port 3, as shownin adeniteratio-as, forinstance,

eight or ten to one-so that when the liquidis passing with the same pressure through equal lengths of the said ports measured in the line of the axis of the inlet-passage c, the amount (No model.)

passing through the outlet c will be in the same proportion to the amount passing through 5o the outlet b as the width ofthe port 2 is to that of the port The passage c communicates directly through suitable pipes, f, with the faucet or main outlet g, the amount flowing through which is to be measured. The inlet-passage a, 5 5 from which the ports 2 3 open, is provided with a valve or plunger, h, adapted to pass through the said passage a suflicient distance to wholly close the ports 2 3, the said plunger having a guide, h', in the chamber b, and be- 6o ing provided with a stem, h2, passing through a guide in a cap, h3, at the upper end of the said chamber I), the saidstem being provided with a pin, 7a4, arresting the downward movement ot' the valve h when the ports 2 3 are 65 fully closed. The plunger is pressed downward to close the ports by gravitation, and it will be seen that the tluid in the chamber b acts upon its upper surface, so'that the iiuidpressure upon it is substantially balanced. 7o When the outlet or passage g is opened, the pressure of the iiuid in the inlet-passage a will raise the plunger h, opening the valves 2 and 3, the movement of the plunger being proportionate to the amount of liquid iiowing through. Theliquid passing through the port 3 and escaping at the passage e ilows through a passage, i, into a passage, lc, communicating with the pipe f, leading from the outlet c. The said passage k contains a measuring-screw of 8o steep pitch, pivoted in a step or bearing, n, at its lower end, (see Fig. 4,) and having at its ripper end a shank, m', passing loosely through a bearing, a', and pivoted in an adjustable pivot-piece, o, at its upper end. The shank m ofthe said screw is provided witlra worm engaging a worm-gear, p, forming one vwheel of a train of speed-reducing wheel-Work,- the arbors of which are provided with pointers, and constitute anindicating device, R, of usual 9o construction, it being inclosed in a case, r, communicating through the bearing nwith the passage i', and consequently subject to the pressure ot' the fluid being measured. An air- 4chamber, t, communicating with the passage 95 ,is employed,so that when the outlet is opened there will be a sudden impulse upon the liq uid, causing it to set the screw m rotating with certainty. By this arrangement it will be seen that a delinite portionfor instance, oneeighth or one-tenthof the liquid drawn from the faucet or outlet is measured, and by a simple multiplication,which may be provided for in the indicating device, the whole amount will be determined.

Then desired to measure all the liquid directly, the chamber b maybe omitted, and the liquid"lct in ati' would all pass through the passage k and thence to the outlet. By placing the recording apparatus in a tight cha-inber communicating with the pipe from which the liquid is drawn, no packed joints are required, and the serewand indicating mechanism require only a very slight force to actuate them. rIhe liquid being measured does not How through the chamber fr, which hasatransparent face, and may, if desired, be filled with a lighter liquid than that being measuredsuelni'or instancc,as oil-which will remain under a statical pressure, and will offer scarcely any resistance to the slow movement of the wheel-work.

I claimrlhe combination ol' the chamber b and its inlet-passage, having two ports in the sides thereof at the same level, and a valveguide, forming a continuation ol" the said inlet-passage, with the valve-plug li, longitudinally movable in the said passage, and `controlling both ports simultaneously, the outlet-passages f and i, communicating with the said ports independently, and the connecting-passage and measuring-screw mA therein, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

XICHOLAS SEIBERT.
